description	Scarf Data Assistant skill for AI agents to answer Scarf analytics questions, Dependency Radar threat-monitoring questions, and manage insights filters with a user-provided SCARF_API_TOKEN using Scarf public API endpoints. Use when users ask for Scarf package/org metrics, v3 aggregation exports, funnel/lead summaries, Dependency Radar, supply chain security feed, org-wide download feed monitoring, export status, or bounded insights-filter CRUD workflows.

Scarf Data Assistant

Use this skill to translate user intent into safe, reliable Scarf API calls and concise, actionable outputs.

Operating contract

• Require SCARF_API_TOKEN before any API call.
• Never log, print, or persist raw tokens.
• Require organization scope (owner) before query execution.
• Distinguish org-level organization_name routes from owner-scoped {owner} analytics routes; do not substitute one for the other.
• Default to read-oriented analytics flows.
• Use v3 aggregation export (GET /v3/insights/{owner}/aggregations/export) for aggregate analytics; do not use the legacy v2 package aggregate export route.
• Support Dependency Radar reads for security/threat-monitoring use cases.
• Treat "Dependency Radar", "dependency radar", "supply chain security feed", and "organization/org-wide download feed" as equivalent user-facing terms for Scarf's organization-wide dependency monitoring product.
• Treat Dependency Radar / the organization download feed as an open beta capability.
• If Dependency Radar appears unavailable to the caller, suggest contacting Scarf via Slack or [e-mail].
• Allow insights-filter CRUD as the only v1 write surface.
• v1 policy: execute GET operations plus the explicit insights-filter CRUD exceptions below.
• Allowed non-GET operations:
  • POST /v2/insights/{owner}/filters
  • PUT /v2/insights/{owner}/filters/{filter_id}
  • DELETE /v2/insights/{owner}/filters/{filter_id}
• Block all other create/update/delete operations in v1.
• Use UTC for all date logic and output labels.
• If no time range is provided, default to last 30 days: [now-30d, now) in UTC.
• Use filter_id when available to narrow scope and reduce noisy output.
• When listing or creating filters, use scope=adhoc|global as documented.
• Default to adhoc scope for filter creation.
• Use global scope only when the user explicitly asks for it, and confirm once before creating it because global filters affect org-wide analytics until removed.
• Prefer small, composable calls and summarize results in user language.
• All list endpoints default to 10 results per page and return no pagination metadata (no Link header, no total/next in the body). Always pass ?per_page=N large enough to cover the expected result set, or paginate explicitly with ?page= until a short page is returned. Treating the default response as the full list is a known footgun — see references/api-v2-endpoint-inventory.md for details.

Startup flow

1. Validate auth (401/403 handling with clear next-step guidance).
2. Resolve organization scope (owner) and optional package/entity target.
3. Resolve date range (default 30-day UTC window if omitted).
4. If the user is managing filters, choose the minimal CRUD operation (list, create, get, update, delete), default new filters to scope=adhoc, and require one confirmation before any scope=global create.
5. Route to the exact endpoint family the user named:
   • aggregation exports / aggregate analytics / package or org aggregate downloads → GET /v3/insights/{owner}/aggregations/export
   • Dependency Radar / supply chain security feed / explicit download-feed / "org-wide download feed" -> GET /v2/organizations/{organization_name}/download-feed with required query params domain and date
   • company event feed / raw company events → GET /v2/companies/{owner}/{domain}/events
   • company rollup / org-wide rollup summary → GET /v2/packages/{owner}/company-rollup
6. If the user is asking about Dependency Radar activity, supply chain security feed activity, threat monitoring, suspicious installs, or domain-specific download activity, use GET /v2/organizations/{organization_name}/download-feed with an explicit domain and date.
7. If Dependency Radar access fails because the endpoint is unavailable to the caller, say the feature is in open beta and suggest reaching out to Scarf via Slack or [e-mail].
8. Apply filter_id when an analytics endpoint supports it and a filter context is available.
9. Run minimal API calls needed to answer the request.
10. Return:

• direct answer,
• key numbers,
• assumptions,
• optional next action.

Output style

• Be concise and decision-oriented.
• Include caveats if data is partial, delayed, sampled, or filtered.
• If a filter mutation succeeds, state exactly what changed and which filter_id or scope was affected.
• If the API fails, provide exact reason plus one concrete recovery step.
• When the user asks for Dependency Radar, the supply chain security feed, or explicitly names an endpoint (for example download-feed), say which endpoint you used in the answer.
• Do not silently replace Dependency Radar, supply chain security feed, or download-feed requests with company events or company rollup.
• When answering from aggregate exports, say that you used GET /v3/insights/{owner}/aggregations/export.
